Hello all you wise people. I am in the process of renovating a detached rural house with a thatched roof and I need loads of advice please. For starters, can anyone tell me about insulation underneath a thatched roof?
I have removed all internal partitions and ceiling on the first floor to create a huge open plan space with a cathedral ceiling. All supported with oak 'A' frames. At the moment the underside of the thatch is exposed and there is no felt.
So I need a layer of really effective insulation. I am planning on using Thinsulate stapled across the rafters. Then a layer of batons followed by plasterboard.
So here come the questions:
1) is Thinsulate sufficient on its own or should I also use something like Celutex as well? (the rafers are not very deep so it would be difficult to get Celutex in there).
Thanks Welshbrickie and windowsill, that is really interesting. I have never heard of this product and all I can find on the net is an adhesive. Is Spraybond something you spray underneath the thatch? Do you know who makes it? Can I put plasterboard underneath? I would really like to know more.
